PLUMBING-FIXTURE.-

and useful Improvements in Plumbing-Fix tures,of which the following is aspecification.

The invention relates to closet constructions and the like, and particularly to the construction of the flushing rim of the bowl.

The invention has for its primary objects; the provision of means whereby the flushing from the rim shalloccur. from a level as near to the top of the bowl as possible, thus rendering the washing of the walls more complete and the fixture more sanitary; the provision of a bowl in which-the overhanging ledge of the flushing rim is substantially eliminated, thus permitting a better observation of the entire inner surface of the bowl and insuring that the surface will receive more thorough attention in cleaning; and the provision of a rim construction in which provision is made for supplying the bowl with a proper amount of water after the flushing thereof. Certain embodiments of the invention are illustrated in the accompanying drawings, wherein.

Figure l is a vertical section through the bowl and its supporting mechanism, Fig. 2 is a section through the upper portion of a modified type of bowl, Fig. 3 is a section through another modification, Fig. 4' is a section through a portion of the rim ofstill another modification,.Fig. 5 is a face view of the collar employed for tightening thepacking, and Fig. 6 is a face view of the head of the stud employed for taking the thrust of the bowl.

Referring to Fig. 1, the principal parts shown are as follows; 1 is the bowl having in its rim the flushing cavity 2; 3 is a horizontal portion of the soil pipe; t is a coupling sleeve or flange; 5 is the packing around the coupling sleeve or flange; 6 is the collar for tightening the packing, suchcollar being operated by means of the bolts 7 8is a bolt for securing the bearing shelf of the bowl to the flange of the coupling 4:, and 9 is a stud. threaded into the flange of the member and adapted to take the thrust of the bowl. The head of the stud 9 is proivided with a slot ltl as. indicated in Fig. 6,

which this adjustment occurs is concealed bymeans of the headed screw 11.

The inner wall 12 of the cavity 2 is provlded near-its upper edge with a series of downwardly directed flushing passages 13 so that the water for washing the bowl is su lied as nearly as possible, to the upper edge of the bowl, thus giving a more complete cleaning effect than if located lower down or at the bottom of the flushing cavity as has been done heretofore. The arrangement, involving the doing away with the usual overhang, also permits of substantially the entire inner surface of the bowl being observed from above, thus insuring that the bowl will be kept in better condition. The bottom of the cavity 2 is inclined as indicated by the dotted line 14, and a small passage 15 leads through the bottom of the cavity at its lowest portion, the apparatus thus providing a refill for the bowl after the flushing operation is completed. The inclined bottom of the cavity provides for the entire emptying of the cavity.

Fig. 2 illustrates a modification in which the cavity 16 is, provided with the downwardlydirected flushing passages 17, such passages being so shaped that the. water is directed along the inner surface of the wall 18. This construction has the advantage that the entire inner surface of the bowl, clear to its upper edge is plain and without any suggestion of an overhang, thus improving the appearance of the bowl'and rendering it more sanitary. A passage 19 is provided to permit of a refill-from therim cavity as in the other type of apparatus.

Fig. 3 illustrates another modification of the rim wherein the cavity 20 is provided with downwardly directed flushing open.- ings 21 for supplying water along the inner surface of the wall 22, the drainage of the cavity being secured by means of the passage 23. v

Fig. 4 shows a form of rim in which the inner wall 24 is substantially plain and upright, and thesurface thereof can be observed from above, although it is inclined inward somewhat. In this form of rim the refill and a part of the flushing occurs through the openings25 leading from the lower portion of the rim cavity 26. The washing of the upper portion of the rim is secured by the use of spaced flushing passages 27 arranged to direct the water circumferentially, the passages being preferably tapered so that the ,water spreads out as indicated by the dotted lines 28. rThe' downwardly directed flushing passages in 3 this and the other forms of devices heretov fore described are also preferably tapered, in the manner commoninj the art,to cause the water to spread ma fan' shapeand wash having an annular flushing cavity around 1ts 'upperedge, the-inner wall thereof being throughout substantially plain and upright, and being provided at its upper portion with flushing passages so as to wash the surface of said inner wall below said p'as'sagejsiZthe wall of thebowl below the said inner wall forming a continuation of said inner Wall and in substantial alinement therewith.

3. A plumbing fixture, comprising a bowl having its inner surface from the bottom to the extreme upperedge substantially smooth and continuous and without an overhang, an annular-flushing cavity surroundingth'e upper portion of the bowl cavity and supply passages extending through the wall between the bowl cavity and flushing cavity adjacent the extreme upper edge of the bowl cavity and directed so asto wash the interior surface of the bowl.
